[Cerebral hemorrhage induced by low-dose streptokinase: a pharmacologic paradox? Report of a clinical case].
A case of an important intracranial hemorrhage after a low dose (approx. 500,000 UI) of streptokinase in a 60 year-old woman suffering from myocardial infarction is presented. Clinical, electrocardiographic, echocardiographic, lab and tomographic findings are described. The authors suggest a pharmacokinetic mechanism which could be responsible of a "paradox effect" (a powerful and dangerous effect of the drug when given in low dose) and they wonder whether in case of allergic reactions should it be better not to stop the infusion of the thrombolytic drug and be more liberal with the "symptomatic" drugs. Tha patient is still alive and the clinical conditions slowly progressing.
